List tasks linked to an entity

List the tasks of any project linked to a Factuarea entity (entity_type + entity_id): an invoice, quote, pro forma, delivery note, purchase invoice, recurring invoice, contact, product or employee.

Archived tasks are included and flagged.
An entity that does not exist or belongs to another company returns an empty list.
Cursor-paginated: pass the next_cursor of a page as starting_after to get the next one; has_more tells whether there are more.

Query Parameters

entity_type*string

Type of the Factuarea entity the tasks are linked to: invoice, quote, proforma, delivery_note, purchase_invoice, recurring_invoice, contact, product or employee.

Value in

"invoice" | "quote" | "proforma" | "delivery_note" | "purchase_invoice" | "recurring_invoice" | "contact" | "product" | "employee"

entity_id*string

UUID of the entity. An entity that does not exist or belongs to another company returns an empty list, never an error.

Formatuuid

limit?integer

Number of tasks to return. Integer between 1 and 100. Defaults to 25.

Range1 <= value <= 100

starting_after?string

Cursor for forward pagination: the id of the last task of the previous page (the next_cursor you received). An id that is not in this list returns 422 invalid_param_value.

Formatuuid

Headers

Factuarea-Version?string

Pin the API version (YYYY-MM-DD, Stripe-style date versioning) for this request; omit to use the key's pinned version, or the latest if none. Unsupported version → 400 unsupported_api_version; malformed → 400 parameter_invalid_format. The effective version is echoed in the Factuarea-Version response header. See the Versioning guide.

Formatdate

X-Active-Profile?string

Operate on behalf of a child company (gestoría master key): pass its public id (UUID v7) and the request runs against that child's data without changing the key's scope, tier or environment (omit to use the key's own company). Invalid UUID → 400 parameter_invalid_uuid; unknown or non-owned id → 404 profile_not_found. See the Acting on behalf guide.
